Specification bf Letters Patent.

Patented Dec. 12, 1905.

Application filed October 23, 1905. Serial No. 284,001.

To all whom. it may concern:

and to also provide whatever adjustment the various appliances may need.

In the drawings forming part of this specification, Figure 1 is a sideelevation of alisterbeam having secured thereto the different parts thatconstitute a complete attachment for the soil-cutting appliances. sideelevation of a beam and attachment equipped with a seed-tube having ashovel thereon, a root-cutter, and a frame furnished withcovering-shovels. Fig. 3 is a diagram of a sweep. Fig. 4 is aperspective representation of a middle-breaker. Fig. 5 is a sideelevation of a beam and attachment equipped with a root-cutter, aseed-tube, a subsoiler, and a frame having covering-shovels. Fig. 6 is aplan of Fig. 5. Fig. 7 is a perspective detail of a subsoiler, and Fig.8

is a plan of the pair of plates that comprise the primary element on myattachment.

The beam 1 has the usual downward extension at its rear end. The plates2 and 2 are adapted to be secured to the beam and to provide forconnecting all other parts. To accomplish the desired end, the plates 22 approach each other throughout their intermediate parts to a distancecorresponding with the thickness of the standard of the subsoiler.

They are turned apart at their front ends, as,

ferent elevations to provide for the attaching- Fig. 2 is a bolt 33 ofthe covering-frame, and the bosses 11 are bored to. admit thesecuring-bolt 11 of the subsoiler-standard.

The shank 11 is divided throughout its upper part. It straddles thedownward-extended end of the beam and the plates thereon. It is pivotedat 12 to swing vertically backward and forward, and its upper end 13 isadjustably secured to the plates. To provide for the adjustment of theshank, the end 13 is slotted at 1-1 concentric with the pivot 12 and isserrated in itsouter faces. Washers 15 are serrated to conform to theserrations of the. shank, and the shank is clamped in place by a boltextending through the slot 14, through the washers, and through theplates and the beam.

A bracket 17 is carried on clamping-bolts 32 of the attachment-plates.It has a horizontal extension projecting rearwardly, and a rod 18 ispivotally conjoined to the rear end of the horizontal extension of thebracket. Beam-bars 30 for the covering-shovels 24 may be secured to theattachment-plates through either of a set of holes through bosses 10,and they are curved to bring their lower rear ends into position toproperly carry the shovels. A crossbar 22 acts as a strut-brace to holdthe shovel-beams a proper distance apart, and it is secured in place bybolts 23. A plate 21 is secured to the cross-bar at the longitudinalcenter thereof, and it has a horizontal surface which is directly overthe rear extension of bracket 17 and isbored to receive the rod 18. Theupper end of the rod 18 is threaded. A lock-nut 19 is screwed ontothe-threaded end of the rod, and upon the rod between the nut and'theplate 21 is placed a compressionspring 20.

The seed-tube 16 is clamped between the rearward extensions 4 of theattachmentplates. It may be provided with a shovel 26, and it may beshifted vertically to vary the depth of cut of the shovel by looseningbolts 32, making the shift, and retightening the bolts.

The intermediate surfaces of the attachment-plates and the ribs 6 6thereon form a recess 9 for the standard 27 of the subsoiler 28. Thestandard has a plurality of holes at dilferent heights, and thesubsoiler is held higher or lower by inserting securing-bolt 11 throughthe holes 11 of the attachment-plates and through an upper or lower holein the subsoiler-shank.

The root-cutter, which is a short runnerformed blade, is demanded whereroots prevail. The shovel on the seed-tube provides a depression orfurrow to receive the seed, and when the subsoiler is substituted forthe shovel the seed is supplied with a bed of loose fine soil upon whichto fall.

The covering-shovels may be adjusted with relation to pitch orinclination by raising or lowering the hitch of the beams on theattachment-plates, and the tendency of the shovels to enter the soil maybe varied by screwing nut 19 up or down on rod 18, and thereby weakeningor increasing the beam-lifting tendency of the spring 20. The shovel 26and the subsoiler are adjusted with relation to the attachment-plates,as hereinbefore explained, the tube 16 being raised or lowered in thecase of the shovel and the standard being shifted between the plates inthe case of the subsoiler.

The sweep, the middle-breaker, and the rootcutter are each adjusted asto pitch or inclination by swinging the shank on pivot 12 and securingit in place.

The beam 1 is lowered more or less to determine the general depth of cutof the soil-cutting appliances.

What I claim as new, and desire to secure by Letters Patent, is

1. In a lister-planter, the combination of a beam having a downward rearextension, a pair of plates secured to the downward extension of thebeam and projecting rearward therefrom, a seed-tube clamped between theprojecting parts of the plates, and a shank for soil-cutting appliancesswingably adjustable on the plates in approximate alinement with thedownward extension of the beam.

2. In a lister-planter, the combination with a beam having a downwardrear extension, of a pair of plates attached to the downward extensionof the beam on opposite sides thereof and projected rearward therefrom,a seedtube clamped between the rearward extensions of the plates bybolts inserted through the plates in the rear of the tube, a bracketheld in place by the tube-clamping bolts and extended rearward from thetube and a pair of perforated bosses on the outer surfaces of the platesin front of the tube, for the attachment the downward-terminating beamthereof, of a v pair of plates attached to opposite sides of the beam,extended rearward out of contact with each other for a distancesuflicient to form a space for a subsoiler-standard and shaped toreceive a seed-tube between their rear ends, bolts for clamping theplates onto the seedtube, a bracket held in the rear of the seedtube bythe tube-clamping bolts and extended rearward, a pair of shovel-beamspivotally hitched to the plates in front of the seed-tube, a cross-barconjoining the shovel-beams, a plate on the cross-bar, a threaded rodpivotally connected with the rear end of the bracket and extendedthrough a hole in the plate on the cross-bar, a nut on the threaded endof the rod and a spring on the rod between the nut and the plate.

4. In a lister-planter, the combination with the downward-terminatingbeam thereof, of a pair of plates attached to opposite sides of thebeam, extended rearward therefrom and forming between their extendedsurfaces a recess for a subsoiler-standard, a recess for a seedtube anda space for a spring-rod bracket.

5. In a lister-planter, the combination with the downturned beam of theplanter of a pair of plates attached to opposite sides of the beam andextended rearward therefrom, a seed-tube clamped between the rearextensions of the plates, a shank for soil-cutting appliances pivotedbetween its ends on the lower, front corners of the plates andadjustably secured to the plates at its upper end, a bracket secured tothe plates and extended rearwardly therefrom, beams for covering-shovelspivotally connected with the sides of the plates, a crossbar for thebeams of the covering-shovels, a plate on the cross-bar, a rod pivotallyconnected with the rear end of the bracket and extended through a holein. the plate, a nut on the threaded end of the rod. and a spring on therod between the nut and the plate.

In testimony whereof I sign my name in the presence of two subscribingwitnesses.
